For 11.0, I needed to install 'pam-modules-32bit' to enable the GUI login to work.

Thanks to the Ubuntu folks for these next steps ([4]). It's been suggested that if net-snmp is already installed, the first two steps are not necessary.

service dataeng enablesnmp

service snmpd restart (if the previous command indicates this is necessary)

service dataeng start

I was then able to see valid output from (e.g) omreport chassis nics

Notes/Caveats

If you see "Failed to start because system is not supported", edit the file /opt/dell/srvadmin/sbin/CheckSystemType , find the IsDELLSystem() function, and replace "OEM String 1" with "Vendor", per [5]
